STEAM STEERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 239,464, dated March29, 1881.

Application filed January 8,1881. (No model.)

To all whom it may concern:

Be it known that I, MARK A. Duns, a citizen of the United States,resident at Scranton, in the county of Jackson and State of Mississippi, have invented certain new and useful Improvements in SteamSteering Apparatus; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification, in which- Figure 1 is a plan view; Fig. 2, a detail.

This invention relates to apparatus for steering vessels.

The invention consists in the construction hereinafter described, andparticularly pointed out in the claim.

In the drawings hereto annexed, A is a cylinder, located at any desiredplace on shipboard. Through the stuffing-boxes B B the piston-rod 0passes, having a length more than twice that ofsaid cylinder, and havingthe eyes 0 c at its ends and the piston D at its middle. The ends of therod (J are connected to the rudder-chains E, which run around sheavesand are connected to the tiller of the rudder.

F is a steam-supp] y pipe from the boiler, connected, by the valve G,with the pipes H H leading through the ports h h into the ends ofcylinder A.

I is a discharge-pipe.

The valve G is preferably a four-way cock, but may be any kind suitablefor the purpose, saidvalve being operated by arod running tothepilot-house. By operating this rod steam is admitted from pipe F,through valve G and one of the pipes H or E, into one end of cyl- Tokeep the piston, and consequently the rudder, stationary a spring-valve,P, is seated at the outlet of pipe I, so as to close the same exceptwhen there isa'direct action of the ex haust during the mot-ion of thepiston, and by such closing to produce a back-pressure of the steam,counteracting the tendency of the expansion of steam in front of thepiston to force the latter forward and turn the rudder.

Pistons having their rods connected, by chains and the like, to thetiller of the rudder of a vessel have been employed in steeringapparatus, and protection only is asked herein for the constructionshown and described and hereinafter specifically claimed.

What I claim is In a steering apparatus for vessels, the combination ofthe cylinder A, having the pipes H H, piston D, and rod 0, connectedwith the chains E E, attached to the tiller of the rudder, the boilerhaving steam-supply pipe F, connected with the cylinder A, and the-pipeI, having the spring-valve I located therein, substantially as and forthe purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

MARK ASHLEY DEES.
